COMMISSIONERS COURT ORDER NUMBER
Kerr County Water Availability Requirements
1.00 An Order establishing Kerr County Water Availability
Requirements for property located in Kerr County outside the city limits of an
incorporated or chartered municipality.
BE IT ORDERED and ADOPTED by the Commissioners Court of Ken
County, Texas:
1.01. General:
Kerr County has been designated as a county within a Priority Groundwater Management
Area by the State of Texas. Therefore, pursuant to Chapter 35, Section 35.019, Texas
Water Code, the Kerr County Commissioners Court has the authority to require any
person seeking plat approval to show:
(1) Compliance with Water Availability Requirements adopted by the
Commissioners Court; and
(2) That an adequate supply of water of sufficient quantity and quality
is available to supply the number of lots proposed for the platted area.
1.02. Water Availability Requirements:
All subdivisions in Ken County where preliminary plat approval is granted after the
approval date of these Water Availability Requirements shall comply with the provisions
set forth herein. Failure to satisfy the Water Availability Requirements shall result in the
denial of approval of the
A. Minimum Countywide Acreage and Lot Size Requirements.
A subdivision that meets the minimum acreage requirements asset forth in Section 1.03
below shall be deemed to have satisfied these Water Availability Requirements.
Kerr County minimum countywide acreage requirements aze based on current county
and regional data that is available. The minimum countywide acreage requirements are
based on an average family or household in rural azeas based on census data and an
average daily consumption that is reasonable for this county based on accepted regional
criteria. The minimum countywide acreage requirement standard is further based on the
State of Texas population and demand analysis; sustainability of the Edwazds -Trinity
Aquifer and the Trinity Aquifer and maintaining adequate spring flow to maintain the
base flow in Guadalupe River and its tributaries.
KC Sub Rules & Regs Revision Page I
The data and information considered in developing the minimum countywide acreage
requirements included but was not limited to:
Texas Water Development Boazd State (TWDB), State Water Plan of Texas;
The Plateau Water Planning Group -Region J, approved and proposed Regional
Water Plan;
TWDB Groundwater Availability Model for the Trinity Aquifer;
TWDB Groundwater Availability Model for the Edwazds - Trinity Aquifer;
Headwaters Groundwater Conservation District, Rules and Regulations;
Kerr County OSSF Rules and Regulations
Complying with these requirements does not insure the developer or prospective lot owner
that adequate groundwater is available under any subdivision or lot.
Kerr County Water Availability Requirements do not ~ 'other requirements that may
be placed on water usage by other entities. Headwaters Groundwater Conservation District
(HGCD) may set pumping limitations on certain aquifers within Kerr County and such
limitations may limit the amount of groundwater available in subdivisions or individual
subdivision lots.
Community water systems will be subject to additional monitoring and testing by HGCD
and TCEQ. For this reason there is a lesser acreage requirement for subdivisions that
utilize community water systems.
The High Density Development Areas aze located in azeas where surface water is currently
being used to meet a portion of the water demand or in areas where there is a reasonable
likelihood that surface water will be available
in the future. For these reason a lesser acreage requirement for subdivisions in these areas
is appropriate.
B. Monitor Well Requirements
Lack of data on the aquifers within Kerr County is a limiting factor in determining water
availability on a more localized basis throughout Ken• County and is a factor in developing
and adopting countywide acreage and lot size requirements. In an effort to improve ground
water models and water availability requirements the following shall be required:
HGCD may waive this requirement by providing the devel
with a letter stating that a monitor well location is not required for subject subdivision.
1.03. Acreage Requirements to meet Water Availability:
KC Sub Rules & Regs Revision Page?
